Replacing the front pillar of the body side panel in assembly with the door hinge (electric welding in a protective environment)
Shine the wing and the door on the corresponding side. Mark the part to be removed. Drill the welding spots and cut out the piece of the rack to be removed together with the hinge. Straighten along the perimeter of the cut out part and prime the metal with a zinc-containing primer. Prepare a new part and check the conformity of the shapes of the part and the hole. Spot weld the part (gas welding in a neutral environment in hard-to-reach places).
Weld the part with short seams to the upper mudguard reinforcement. Clean the seams. Restore the protective coating of the bottom. Restore the paintwork. Treat the closed cavities with liquid wax.
Replacing the front pillar of the body side
Remove the wing and door on the corresponding side. Mark the parts of the pillar and bottom to be removed. Drill out the welding points and cut out the pieces to be removed. Straighten the perimeter of the cut out part and prime the bare metal with a zinc-containing primer. Prepare the patches (the replaceable part of the bottom is installed with an overlap) and check the conformity of the patches and holes. Spot weld the patch to the pillar and bottom (gas welding in a neutral environment in hard-to-reach places). Weld the bottom with a continuous seam along the perimeter. Clean the seams. Level the surface with tin (if necessary). Restore the protective coating of the bottom. Restore the paintwork. Treat the closed cavities with liquid wax.
Note: The process for replacing door hinges is described below.
